JOHN KREHBIEL, OF DETROIT, MICHIGAN, ASSIGNOR TO THE GLOBE CAP- SULECOMPANY, OF SAME PLACE.

CAPSULE-CUTTER.

SPECIFIC'A'IICC.T forming part of Letters Patent No. 312,361, datedFebruary 17, 1885.

(No model.)

To all whom it may concern:

Be it known that I, JOHN KREHBIEL, of Detroit, in the county of Wayneand State ot' Michigan, have invented new and useful Improvements inCapsule-Cutters; and I do hereby declare that the following is a full,clear, and exact description'thereot, reference being had to theaccompanying drawings,

which form a part of this specification.

rIhis invention relates to certain new and useful improvements in theconstruction and operation of devices for cutting gelatine capsules fromthe molds upon which capsules are formed.

The invention consistsin the peculiar construction of the various partsand their coinbinations and operation, as more fully hereinafterdescribed.

Figure l is a perspective View looking toward the front ofthe device.Fig. 2 isa like View taken from the reverse side. Fig. 3 is across-section through one of the series of cutters.

In the accompanying drawings, which form a part ot this specification, Arepresents the front, and B the rear, plate, through Awhich are formedthe coincident holes a b, and between these plates is a plate, C, 0fsheet rubber, with holes coincident with the holes c b, but of largerdiameter. Ring critters D,

sharpened on their inner periphery or edge, are fitted into the holes inthe rubber plate, and held in place by the front and rear plates` whichare secured together by the rods J E and nuts c d. These rods alsoproject from the reverse side oi' the device, and are provided withadjusting stop-nuts e. In order to allow these stop-nuts to be adjusted,the rods are suitably threaded; or any other form of an adjustable stopmay be employed without departing from the spirit of my invention.

In practice the stops are adjusted to the length the capsule is desired,such length being regulated by the distance between the 45 stop and theface ofthe plate B. The device then is grasped by the hand of' theoperator, and the projecting ends of the rods entered into coincidentholes in a plate of molds, which I make the subject-matter of a distinct5o application for a patent, and hence do not describe in thisspecication. rIhe mold-pins of such mold-plate, being arranged in seriescoincident with the series of holes in this cutting device, enter thering cutters until the stops are brought into contact with the front ofsuch mold-plate. A rotary motion is then communicated to the platescarrying the ring cutters by the hand ot" the operator, which brings thecutting-faces into contact with the capsules on the mold-pins and cutsthem off 6o in uniform lengths. The pressure necessary to perform thiscutting is exerted through the rubber plate, the elasticity of whichwill allow of any slight variation of the mold-pins without interfering`with the perfect work of the cutters. y

I am aware ofthe Patent No. 297, 380,granted to James II. Glover, April22, 1884, and make no claim to the construction shown therein as formingpart of my invention.

I am aware that it is not new to employ in a capsule-cutting machine acutter-plate constructed with an orifice surrounded by an annularbeveled cutting edge projecting inwardly toward the center oftheorifice.

I am also aware that it is not new to employ in a capsule-cutting-offdevice a ring cutter inserted in a rubber spring-plate and cutting uponits inner periphery.

Vhat I claim as my invention isl. rIhe combination, in a capsule-cuttingmachine, of an annular cutter sharpened on the inner edge and held in asuitable holder, a mold-pin attached to a suitableholder, and anadjustable guide attached to one of said holders for regulating theposition of the pin as to its length within said cutter, substantiallyas described.

2. In a capsule-cutter, a series of ring cutters set in a` suitableholder, and a second 9o holder carrying a series of mold-pins, one ofsaid holders being provided with a series of guide-rods and the otherholder with a correspondingseries of guide-holes in which saidguide-pins work, substantially as described.

3. A capsule-cutting-off device consisting of the following elements:rigid front and rear plates, inclosing a spring-plate, through all ofwhich are coincident holes, those in the springplate inclosing ringcutters, stops, and guideroo rods, the parts being constructed,arranged, and operating substantially as and for the purposes set forth.
